Properties

Properties are required only for uncommon fluids, such as polymers, heavy hydrocarbons (e.g. asphalt), oils, and proprietary fluids. Common fluids include water, common solvents (e.g. acetone), light hydrocarbons (C1 - C6), and most industrial heat transfer fluids (e.g. Syltherm, Dynalene, Mobiltherm, Therminol, etc.).
